The CPU in 360 is called Xenon and it's virtually identical to 3x ps3 PPE (PPE is Cell sans the SPEs). Both Xenon and Cell had considerable FLOPS power (Cell in particular, thanks to the SPEs), but both had major general-purpose issues. Anyhow, if that will help get this thread back on track, here's a direct comparison between ps3 PPE (remember, identical to Xenon), and Cortex A57:
7zip LZMA benchmark charts:
(1st numerical colum is num threads, 2nd is clock, 3rd and 4th - compress and decompress score, resp)
Code:
IBM Cell PPE
1 core, 2 threads 1 3200 720 1060
2 900 1500
4 1000 1500
Code:
AMD Opteron A1170 (Cortex-A57)
8 cores
64-bit (aarch64) 1 2000 2160 2040
8 13200 15800
For an apples-to-apples re the individual cores performance, one should take the 2-thread results for PPE and compare those to the 1-thread result for A57; result for latter should also be halved for clock (2GHz in Opteron vs 1GHz in switch).
Enough from me, I'll let you do your own computations. Now, back on topic.
Man, those gyro controls should be friggin mandatory by now!
